' the Walls of said case being of sufficient thick- Be it known that I,HENRY W. MASON, of} South Goventry,-in the county of- Tolland and Stateof Connecticut, have invented anew and useful Improvement in Uni-BallAmmunition;

and I do hereby declare the following to he a full and exact descriptionof thesame, refer ence. beinghad to the accompanying drawings, forming apart of this specification,and to the letters of reference markedthereon.

" This invention relates toincasing the ball or projectile in apeculiarly-constructed case,

ness that, conjoined with the diameter of the ball, will cause the caseto slug into and fill made of a material that combines the substantive,elements to produce such'results', in combination with acartridge-she'll or powdercase.

The object of this invention is to produce an iucased ball for uni-ballammunition that, when the ball or projectile is made of either steel,

iron, zinc, or 1ead,-or similar material, can be used in rifled arms,and the ball or projectile, in its transit through the rifled barrel,without beingslugged into the grooves or riding, shall receive or havetransmitted to it by said casing a rotary motion, the same as though theprojectile had been slugged into the grooves or rifling in the usualmanner, and the ball or projectile clear itself from the casin g (afterleaving the barrel) at the desired moment-of time; and that, when theprojectile is made of steel, iron, or other. hard material, it will not,in its passage through the barrel, injure the edges of the riiling northe lands thereof, and, when the softer metals are made use of for theprojectile, will render it less liable to strip or upset at its base, todispense with the cannelures and give an equal distribution of thelubricant over the whole of that portion of the projectile-casing thatlies against the lands and that which is slugged into the riding, andthat it may continue with it during its transit through the barrel, thecase to preserve the smooth unbroken surface of the projectile, which,after clearing itself from the casing, will present no rough or 4asperated parts on which, the atmosphere am act to retard itsflight orcause divergence; also, that the dirt or fouling caused by the firstdischarge be'removed and the bore cleaned and lubricated by the casingby the subse- 5 quentdischargaand so on continuously for any number ofdischarges, thus giving a continuous easy transit tothe projectile,avoid -leading, lessen recoil, and'protect the riding from wear; thecase also as an insulator to .6 protect the powder from ltheietiecl ofgalvanic action between the projectile and the metallic cartridge-shell.y

It is evident that for uni-ball ammunition,

especially when a cylindro'conical projectile is 6 used, a casingproducing results-described 'abovew-ill give an increased range andpcnetration, a more flattened trajectory, increasin g the space of danger,lessen recoil,'reduce to a minimum the fatigue caused by continuousfiring, prevent fouling,-'and preserve the arm for a longer period oftime.

To enable those skilled iii the art to make and use my invention, I nowdescribe the manner in which the casing may be made. 7

Figure l-is a longitudinal sectional view of a cartridge. A. is thecartridge-shell. B is the ball, and G the casing.

Figs. 2, 3, 4, 5, and. 6 are similar views of modifications. Fig. 7shows views of the case detached, and illustrates the various forms inwhich the case may be made.

. In Fig. 1 is shown the case closed over the top and base of the ball.Fig. 2 shows thecase closed overthe base but not over the top. Fig. 8 5

3 shows the ease open at the base but closed overthe top. Fig. 4;represents the case divided in equal parts or halves longitudinally.

The case, as shown in Fig. 7, illustrates the different modes in whichthe cases may be divided in part into sections longitudinally, ordivided their entire length.

The tubes for the case'I prefer to be made of fabricated paper andformed by relling on a mandrel in the usual well-known manner, thenseparated in the desired lengths. These lengths are then placedon studsof proper form and size and subjected to the action of dies that firstcorrugate the end in a cone-like form,

and then, by other properly-formed dies, they 1 parafline oil and Wax,or any other desirable are closed, crimped, and compressed into aslitsare required.

dome-like form over the top of the ball and. flattened over the base, asdesired.

The slitting or dividing of the case is done before the ball isinserted. An y of the Wellknown devices may be used for this purpose.The cases are placed in a heated solution of lubricant, and remaintherein until a sufficiency of the lubricant has been absorbed by thecase.

The slits or cuts; as shown in Fig. 7, are for the purposes of moreeasily separating the case in sections after leaving the barrel by thecentrifugal force communicated thereto by the rotary motion given by theriding, which causes the ease to bethrownofl' the ball immediately afterit leaves the barrel.

I prefer to use ,fabricated paper'for these cases; but anyfibrousmaterial that combines the physical characteristics required may beused, and the cases may be formed, when desired, in halves, as shown inFig. 7, in molds from fibrous substances madeina mash. When thus formedin equal half parts no cuts or I am aware that the patent granted to meSeptember 9,1879, numbered 219,491, is for a case of similar character,and which, in the ters Patent, is-

main, embodies the principle of this present required for a uni-ballcartridge; therefore the purpose of this present application is tosecure by Letters Patent the combination of the said casingaudits-modifications, as herein shown and described, \vitha uni-ball andcartridge shell or powder-case and the casing when not so combined.

WVhat I claim, and desire to secure by Let- 1. A case for a projectile,made of fabricated paper or equivalent material, having slits,substantially as deseribed, and for the purposes set forth, incombination with a single projectile." v

' 2. A casei'or uni-ball ammunition, made of fabricated paper orequivalent material, closed at its top and base by compression, anddivided in sections longitudinally by slits 01 cuts, the said slits orcuts, passing along the side and across the base thereof, in combina-Nevertheless theclaims in said tion with a single projectile,substantially as and for the purpose set forth. 7
